Google doesn’t like automation and backlink services
Probably, you have seen advertising tools and services that promised hundreds (if not thousands) of backlinks, which can be obtained with little effort. Hoping to dominate the search results, your website will most likely be banned by Google. If you have many external backlinks it is possible to track using https://sitechecker.pro/backlinks-tracker/ that help analyze all of them.
Beware of tools and services for the automation of external promotion. If you could find these services, the antispam team from Google also knows about them.
